Right-hander Michael Wacha, who has a five-game winning streak but who has had trouble putting hitters away with his fastball, apparently has had more than mechanical glitches with which to deal.
After Wacha was examined Tuesday, the Cardinals placed him on the 15-day disabled list with right shoulder inflammation, then brought up prized right-hander Alex Reyes from the Class AAA Memphis club.
To make room for Reyes on the 40-man roster, the Cardinals transferred injured catcher Brayan Pena (left knee) to the 60-day disabled list from the 15-day DL.
Reyes, 21, considered among the top prospects in baseball, arrived at Busch Stadium on Tuesday and said he has been told he will be used out of the bullpen starting Tuesday night.
In his last game for Memphis on Saturday, Reyes allowed one run and fanned eight in six innings.
After completing his 50-game suspension meted out last year for a PED infraction (marijuana), Reyes was 2-3 with Memphis with a 4.96 earned run average although he fanned 93 in 65 1/3 innings.
Wacha, who made his 23rd start on Monday night, lasted five innings in a no-decision. He is 7-7 with a 4.45 ERA this season in 131 1.3 innings.
